A 30N ball has been thrown vertically up ward into the
air from reference surface. It has been observed that when
the
ball is 20m above the surface, its velocity reaches 30m/s.
Find:
(a) The ball's velocity just as it left the surface.
(b) The maximum height the ball reaches.

Two identical balls, Ball A and Ball B are thrown vertically
upward. Ball A is thrown with an initial speed of
v, and Ball B is thrown with an initial
speed of 2v. Which of the following
statement is correct? Ignore air resistance.
A. The maximum heights of the two balls are equal.

A ball is thrown vertically downward from the top of a
33.0-m-tall building. The ball passes the top of a window that is
10.8 m above the ground 2.00 s after being thrown. What is the
speed of the ball as it passes the top of the window?

A ball is thrown vertically upward from a height of 5 ft with an
initial velocity of 40
feet per second. Note that the acceleration of the ball is given by
a(t) = −32 m/s2.
How high will the ball go? When does the ball hit the ground? What
is the velocity of the ball when it hits the ground?

A ball is thrown vertically upward from the top of a building
112 feet tall with an initial velocity of 96 feet per second. The
distance s (in feet) of the ball from the ground after t seconds
is s (t) = 112 + 96t - 16t2 Complete the table and discuss the
interpretation of each point. t s(t) Interpretation 0 0.5 1 2 100

A stone is thrown vertically up from the top of a tower with a
certain initial velocity. It reaches ground in t seconds .(7.65). A
second stone, thrown down from the same tower with the same initial
velocity reaches ground in 3.6 seconds. Determine (i) the height of
the tower, and (ii) the initial velocity of the
stones.

A ball is thrown straight up from the edge of the roof of a
building. A second ball is dropped from the roof a time of 1.20 s
later. You may ignore air resistance.
A) If the height of the building is 20.7 m , what must the
initial speed be of the first ball if both are to hit the ground at
the same time?
B) Consider the same situation, but now let the initial speed
v0 of the...

A ball is shot up from a surface that is 20 m above the surface
with an initial speed of 10 m/s.
1. What is the magnitude of the ball's displacement from the
surface after 3.00 second has elapsed?
2. What max height will the ball reach from the surface of the
earth?
3. How much time elapses between the throwing of the ball and
its reaching to the earth?
4. Calculate the magnitude of the velocity of the ball...

Part I
A ball is thrown straight up from the top of a building that is
185ft high with an initial velocity of 64ft/s. The height of the
object can be modeled by the equation s(t) =
-16t 2 + 64t + 185.
In two or more complete sentences explain how to determine the
time(s) the ball is higher than the building in interval
notation.
Part II
In two or more complete sentences, describe the
transformation(s) that take place on...
